ll Claim.

This invention relates to waterproof protective devices. In its more specific aspects the invention is concerned primarily with the provision of a limb-incloslng member for preventing the access of water to the enclosed part of a leg or am so that the person whose arm or leg is I bandaged or which for other reasons should be kept dry can bathe without danger of impairing the bandage or without interfering with the treatment of the part oi the arm or leg which must he kept dry.

In accordance with the present invention the protective device comprises a. tubular member or a member having a tubular portion formed of waterproof sheet material, preferably elastic sheet rubber or latex, designed to inclose limb and provided with means disposed internally oi the tubular member or tubular portion and spaced from the ends thereof to form a W&t21'- tight seal whereby to prevent water from reaching the bandaged or other portion of the limb so be desired. The oroteotive device intended i'or use on. logs or moo: which are protitled with bandages of any plaster casts, semi-rigid loos. .og, w dresslogs, etc or for use on arms which are not necessarily bandaged; tit which nevertheless may required to he inept in the treatment there-oi.

In specific of the invention illustrated herein and will hereinafter he described, the protective device is in the form of e for example a thin sheet rulober stocking or glove, depending open wl'iethcr the device to be used for the leg or arm, respectively. timid stocking or glove is oi'suitalole length for ioclosing the desired part oi the leg or am one is provided with one or there watezweollng flanges dispose-d ihterlorly oi the stocking or glove and extending completely thereai'ound adjacent the end through which the leg or arm is inserted. The edge of the stocking or glove at the opening therein is designed to closely ilt limb tor preventing the passage oz water lot lltdlfi of the stocking or glove beyond said edge, end the Water-sealing first pletely thereoround inwardly oi said edge 01 stocking or of glove, prevents any water which might leak past sold edge irom reaching the bandaged or other portion or the arm or leg which it is desired to keep dry.

tective devices illustrated the accompanying" ego or flanges which engage the limb comdrawing, it being understood, however, that said drawing while illustrative of the invention is not limitative thereof.

In the drawing:

Fig. 1 is a perspective view of a protective device embodying the present invention; Fig. 2 is a View illustrating the device show in Fig. l in "use on a bandaged leg;

Fig. 3 shows a protective device in position one, bandaged arm;

Fig. 4 is a view similar to Fig. 3 showing a protective device which is open at both ends;

Fig. 5 is a fragmentary sectional View illustrating the provision of a plurality of Waterseallng flanges adjacent the edge of the tubular I member,

Referring now to the drawing in detail, the protective device ill illustrated in Figs. l. and 2 is shown as a stocking to be tvorn over a bandleg. Said stocking is formed of relatively thin waterproof sheet material such as soft sheet rubber or latex, which is also preferably elastic, and comprises, preferably in integral relation, a foot portion l2 and a leg portion it which for most purposes is preferably long enough to extend above the wearer's 'lmee. Leg portion i l terminates in an edge it, which when the stocking is in position, engages the wearefs thigh with a snug fit whereby to prevent the passage of water beyond said edge interiorly oi the stocking. A water-sealing flange it consisting of an endless band of sci't and elastic sheet rubher or latex extends completely around the stocking interiorly thereof adjac t edge 55. When the stocking is not in us old band projects inwardly and is substantially in a plane at right angles to the peripheral wall of the stocking leg, in which position said hand is self sustaining. The inner edge flange i8 is of less length than the edge 5 oi the stocking leg and is of less length than the line oi? juncture 22 of said flange with the wall of the let; portion M. Flange ill is preferably formed integrally with leg it by molding .fiange together with said; leg portion in a suitable mold, although it will he understood said flange may be formed as an initially separate member and thereafter united leg portion prior to vulcanization of said. flange and of; said leg portion. he understood that flange iii and leg portion i4,

being formed of thin sheet rubber or latex, is

inclosed in said device tor preventing the Itwill entrance of water to the limb.

It will be observed by reference to Figs. 1 and 2 that when the leg is inserted in the stocking, flange I8 is displaced from the substantially horizontal position illustrated in Fig. l. to the downwardly extending position, illustrated in Fig. 2, in engagement with the limb whereby said flange is properly positioned about the limb and snugly engagesthe latter at edge it of the flange as well as through a substantial surface portion of said flange.

In Fig. 3 the protective device is illustrated in use on a bandaged arm. As here shown said device the, which for convenience in reference may be termed a glove, comprises a tubular per-=- tion Ma having an inclosing portion its. Said glove is preferably long enough to extend from the hand to'above the elbow of the arm on which it is worn and is designed so that its edge Mia engages the wearers arm with a snug fit to prevent the entrance of water into the glove. The water-sealing flange iBa is similar in all respects to flange It and is positioned adjacent edge its for engagement with the wearers arm. It will be understood that the inner edge of flange it is of less length than the edge i611 and that when the arm is inserted in the glove said flange is turned downwardly toward the hand. of the wearer. In Fig. 4 the glove illb is similar in all respects to the glove iila except that the tubular portion Mb oi glove Nib is not provided with a hand inclosing portion but instead said tubular portion is open at both ends terminating in edges itb and the designed to snugly fit the wearers arm above the elbow and at the wrist. Flange lltb which is positioned adjacent upper edge it?) of the glove is similar in all respects to flange ita, and in addition there is a water sealing flange itc' which is similar in all respects to flange 6% but is smallerthah the latter for providing the proper water-tight seal at the wearer's wrist or forearm. It will be understood that the inner edges see and the of water-sealing flanges till and i to respectively are of less length than the edges it! and the respectively of tubular member Mb. Gloves its and itb are, like stocking iii, preferably made of thin elastic sheet rubber or other suitable waterproof sheet material, as are the flanges its, iiib and itic.

While in the above described forms of the invention only onewater-sealing flange is illustrated in position adjacent the edge of the limbclosing member, it will be understood that more bandaged part of the than one of said water-sealing flanges may be provided. This is illustrated in Fig. 5 which shows a tubularportion Md of a limb-lnclosing tubular member provided with two water-sealing flanges 68d positioned adjacent the edge 56d of the tubular member, said flanges being spaced from each other longitudinally oi the tubular member. If desired, a third additional flange may be provided.

Thus it is seen that the protective devices illustrated and described herein are well adapted to accomplish the object of the invention. It will be understood, however, that while I have referred to the use of the limb-inclosing memhere in connection with the protection of bandaged arms or legs, the invention is not to be restricted to such use but may be embodied for other purposes, for example, in rubber boots used by fishermen or others, to prevent the entrance of water from the top of the boot. It will be understood further that the invention may be embodied structurally in forms which differ from those illustrated or described herein, and that in the illustrated or described forms certain changes in the construction and arrangement of parts may be made. Therefore I do not wish I to be limited to the invention as herein illustrated or described, except as may be required by the scope of the appended claim.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

A waterproof protective device of the class described comprising a limb-inclosing member formed of waterproof thin sheet material and having a tubular part open at one end through which the limb is inserted and open also at its other end to permit a part of the limb to project therethrough, and an annular strip of waterproof and elastic thin sheet. material disposed interiorly of said tubular part completely therearound adjacent each of said open ends inwardly thereof, the outer peripheral edge of each annular strip being secured to the inner surface oi said tubular part, said strips projecting laterally from said inner surface for engagement of the inner marginal surface portions of said strips with the wearers limb completely adjacent both open ends of said tubular part to prevent water from passing from said open ends to the interior of said tubular part, the opposite ends of said tubular part being adapted to snugly engage the limb to provide with the adjacent strip a double seal at each end of said tubular part.
